Hi @jonathan0104 , hi @sfstar ,
as victron_settings_ess_mode only shows a number for me instead of the ENUM, I checked my system values + the Victron Register list.

Finding:
There are three registers for ESS Mode

• Address: 4609 points to "/Settings/Ess/Mode" with values: 0=self-consumption (battery-life);1=self-consumption;2=Keep charged;3=External control
• Address: 2902 points to "/Settings/Cgwacs/Hub4Mode" with values: 1=ESS with Phase Compensation;2=ESS without phase compensation;3=Disabled/External Control
• Address: 4921 points to "/Settings/Ess/Mode" with values 1=ESS with Phase Compensation;2=ESS without phase compensation;3=Disabled/External Control

Issue:

• "settings_ess_mode" points to register 2902 with values 0=self-consumption (battery-life);1=self-consumption;2=Keep charged;3=External control

Solution idea:

• Change register "settings_ess_mode" to 4609
• I saw that you added the two other registers already in Feature/add all registers that were added to venus since integration inception #274 . --> Switch 4609 with 2902 in PR as well
• Add a second ess-mode enum for 1=ESS with Phase Compensation;2=ESS without phase compensation;3=Disabled/External Control
• Check, why the following fields show int values instead of ENUMS: vebus_mode, settings_ess_battery_life_state, settings_ess_mode
